I never said that. In fact, I expressed my disdain for the idea of taking incremental cuts only to throw it away by cutting a butt sleeve tenon in one session, because of stress. You claim to think most guys don't do it, but I haven't heard anybody refute the notion besides you & you never explained how you actually do it. Regardless, I stated my technique of avoiding internal stress via coring. And yes, I do believe PROPERLY cored woods will not move due to internal stress. Coring by definition means removing the core of a piece of wood to eliminate internal stress. There's more to it than drilling a hole & filling it, as you should know. You have to know what to core with & what size. And you have to know how to choose wood that is naturally stable. Unless you know this stuff, coring will be no good. But if you do know this stuff and thereby core correctly, then you'll not have to worry about movement due to internal stress.
That brings me to a question. In your building experiences, what problems are created by making a cut at final size as deep as a wrap groove? Exactly how much are you cutting for a wrap? I have no troubles doing it, and explained why. My cues speak for themselves, always have. If there was a problem then it should have revealed itself by now.
I never said there was a problem with cutting in increments. Not once. Never. I'm not even sure what you are asking about. The wrap groove is not a deep cut for me. I don't install a wrap thicker than .020" and my finish is .010", so i'm not taking a huge cut to make a wrap groove. Why would I have anything to worry about?
Cuemaking is a science. You bet your ass it is. Rocket science, no. It's pretty simple stuff but requires exacting standards & methods. The science is learning and experimentation. Once you have that knowledge, building a cue is applied science. The science is to build a cue that plays well & lasts. My science is simplicity. Yours, maybe not. I'm not concerned with how you build cues, honestly. My cues last & play well. I'm never shy about discussing my methods. Some of it is my own & I prefer to keep it as such. Doesn't mean it's not simple. You are twisting & misinterpreting what I write & I sense some sarcasm in it. Hopefully i'm wrong about that.
